Abstract

Pituitary stalk interruption syndrome is a rare disease characterized by a deficiency

of adenohypophyseal hormones. Clinical presentation usually occurs in

childhood or in the second decade of life. The severity of hormonal deficiency is

variable. It may be isolated or be accompanied by extra–pituitary anomalies.

Magnetic resonance imaging findings are considered as an absent pituitary stalk,

absent or smaller adenohypophysis, absent or ectopic neurohypophysis.

Contrast-enhanced imaging is essential in evaluating the presence and morphology

of the pituitary stalk. In the presence of clinical findings, evaluation of the

hypothalamic–pituitary region using magnetic resonance imaging is necessary

for diagnosis. Early diagnosed cases can maintain their normal lives with hormone

replacement. In this article, we aimed to present pituitary stalk interruption

syndrome and its magnetic resonance imaging findings with a case presentation
